 NC Helix Drill” cuts a hole by helical interpolation and is designed with optimized grade and geometry for high performance in steel, stainless steel, cast iron and hardened metals.
Serrated cutting edge makes cutting chip short and easily to be removed while drilling. It is not only working like a drill, but also a milling and slotting cutters too. Small radius path is suitable to cut holes, step holes, countersink holes and create various cavity shapes.
One important advantage of NC Helix Drill is it can drill deep hole easily in different diameters just use one tool. And the hole depth is possible up to 6xDc. with internal coolant. Following is the illustration of how NC Helix Drill cut different deep holes by one tool.
